I have the question about electron affinity: Predict the trend for electron affinity across a period. Explain your answer.
I know that it increases from left to right in a period, but I dont know why. Any help is appreciated, thanks.

Think about noble gases and outer electron configurations.

What else increases from left to right in a period? Opposite attracts..
